SPECIFICATION forming part of Letters Patent No. 739,561 dated September 22, 1903.

Application filed May 1, 1903- Serial No. 155,197. (No model.)

To all whom it may concern:

Be it known that I, ALBERT C. S. RUE, a citizen of the United States, residing at N orthwood, in the county of Worth and State of Iowa, have invented certain new and useful Improvements in Hoisting-Buckets, of which the following is a specification.

This invention relates to means-for facili tating loading and unloading of grain and pending means and normally held in upright position by catches adapted to be tripped to effect a discharge of the load when the bucket A has reached the required point.

' to in the following description and indicated For a full description of the invention and the merits thereof and also to acquire aknowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a hoisting-bucket embodying the invention. Fig. 2 is a vertical central section thereoflthe suspending-bail and shaft being in full, parts of the bail being broken away and a portion in section. Fig. 3 is a View of the bucket inverted. Fig. 4 is a perspective view of one half of the substructure or base-frame of the bucket. Fig. 5 is a perspective View showing more clearly the catch mechanism for holding the bucket in normal position, the parts being on a larger scale. of the means connecting the shaft to the bail, an end portion of the bail being in section and the eyepiece being inelevation.

Corresponding and like parts are referred in all the views of the drawings by the same reference characters.

Fig. 6 is a detail view The bucket may be of anycapacity and outline in horizontal section and is preferably constructed of sheet or plate metal of a gage to insure stability of structure anddurability. The bottom ofthe bucket is strengthened and reinforced by a substructure or base-frame composed of a plurality of metal bars preferably of angle formation in transverse section. In the preferable construction the substructure is composed of two halves of similar formation, about as illustrated in Fig. 4:, each half or section consisting of a semicircula bar land guard-bars 2 and 3.

The bars 1 and 2 are preferably channeled, whereas bar 3 is of angle formation. The two halves of the substructure or base-frame are the latter embracing the pendent wings of subjacent bars 3 and bolted or otherwise rig-.

idly attached thereto. (loupling-bars are fitted into the chan nels of curved bars 1 and are secured to the wings by bolts, rivets, or like fasteningspassed through openings in subjacent parts in coincident relation. The substructure or base-frame is of skeleton formation and is provided at diametrically opposite points with bracket-lugs 6 in line with clamp 5 and receiving shaft 7, which is supported in parts 5-and 6 by passing through openings therein in transverse alinement. The terminal portions of shaft 7 project beyond the opposite sides of the bucket and are threaded and receive nuts 8.

The bottom of the bucket is'indicated at length of the bucket-body and are made fast at their upper and lower ends to bands 11 and 12, respectively, and are positively connected at intervals in their length to the portion 10 of the bucket. The upright stays or braces 13 may be of any form in cross-section and are spaced apart a distance to insure firm bracing of the bucket at every point. A side of the bucket is left open and is closed by a series ofdoors 14 and 15, having a superposed arrangement and hinged at one end to the bucket at one side of the opening and adapted to be secured at the opposite end to the bucket-body at the other side of the opening by means of suitable catches 16and 17. The end portions of the bucket-body 10, bordering upon the opening closed by doors 14 and 15, are braced and reinforced by suitable stays or bars in order to provide the requisite resistance to strain and wear. The doors may be provided with one or more catches. As shown, the door 14is provided with upper and lower catches 16, and the lower door is provided with a single catch 17, and these catches are of like formation, being pivoted at one end to the doors and adapted to engage at the opposite end with hook-stops 18, applied to the reinforced edge of the body 10, against which the doors close.

In order to provide convenient means for releasing doors 14 and 15, operating cords or ropes 19 and 20 are provided, the same passing over sheave-pulleys to the upper portion of the bucket adjacent to the opening in the side thereof. Operating-cord 20 is connected to catch 17, and operating-cord 19 is branched,

each branch being connected to one of the catches 16. These cords or ropes 19 and 20 extend within convenient reach of the operator, so as to be pulled upon when it is required to release one or all of the doors, according to the manner of discharge.

The suspending-bail 22 is preferably a tube bent in the form about as shown and provided at its upper end with suspending-clevis 23, consisting of an eyebolt having a swivel connection with the hail, the point of connection between parts 22 and 23 being reinforced by clamp 24, same consisting of similar plates bolted together and having oppositelycurved portions forming seats for reception of bail 22 and eyebolt 23, which passes through an opening in the bail and an opening formed by opposite grooves in the meeting faces of the plates forming the clamp 24. Eyepieces 25 are secured to the lower ends of the seat portions of bail 22 and receive end portions of shank 7, which passes therethrough, the guards or stops 8 retaining the parts in position. The bucket is adapted to turn upon shaft 7 as an axis and is normally held in an upright position by means of pivoted catches 26, of hook-form,clamped to the side portions of bail 22 and adapted to engage with stops 27, projected outwardly from opposite sides of the bucket near its upper end. A catch and cooperating stop are provided at each side of the bucket, and the catch is pivoted to clamp 28 and is held in an approximately horizontal position by stop 29, extending inward from clamp 28. The catches are adapted to be operated by means of cord or rope 30 connected thereto and passed over sheave-pulley 31, applied to each side portion of bail 22 at a point above the bucket, the opposite end of cord 30 extending within convenient reach of the operator. The bucket is limited in its turning movement upon shaft 7 by means of chains or cords 32, attached at one end to the bucket and at the opposite end to the sides of the bail.

The hoisting means (not shown) is adapted to be attached to the bucket by means of clevis 23 in the accustomed manner. After the bucket has been loaded with the commodity to be discharged and same has been elevated or lowered, as the case may be, the load may be discharged in one of several ways, either gradually by opening the doors successively or by releasing the bucket and turning same upon shaft 7, or by a combina tion of these two ways-that is, by releasing the topmost door to permit a partial discharge of the load and then releasing the bucket to permit the discharge of the remainder.

Having thus described the invention, what is claimed as new is 1. A hoisting-bucket having its bottom strengthened and reinforced by a substructure of skeleton formation, and a suspendingbail connected to the bucket by means of said substructure, substantially as described.

2. In a hoisting-bucket, a substructure comprising similar parts or sections, each section being composed of a semicircular bar and parallel guard-bars, a clamp and couplingbars connecting the sections of the substructure, bracket-lugs applied to the sections in line with said clamp, a shaft supported in said clamp and bracket-lugs, and a suspendingbail pivoted to the shaft, substantially as described.

3. In a hoisting-bucket, a suspending-bail having a vertical opening, similar plates clamped to the bail and having grooves in their meeting faces to form an opening in line with the said opening of the bail, and an eyebolt mounted in the registering openings of the bail and the said clamp-plates, substantially as set forth.

4. In a hoisting-bucket, the combination of a suspending-bail, a bucket connected to said.

bail to turn and effect discharge of the load,

a clamp applied to a member of the bail and having a stop, a catch pivoted to said clamp and limited in its downward movement by the stop on the bail,a stop projected from the bucket for cooperation with the pivoted catch to hold the bucket in upright position and means for efiecting a releaseof the catch, whereby the bucket is permitted to turn, substantially as described.

5. In combination, a hoisting-bucket provided in a side with an opening, and a plurality of doorsfor closing said opening and located one above the other and hinged to the bucket at one side of the opening, and means for securing the doors to the bucket at the opposite side of the opening, substantially as described.

6. In combination, ahoisting-bucket, a suspending bail having the bucket pivotally connected therewith, connecting means be- V qaesci tween the bucket and bail to limit the turn: ing of the bucket when turned to effect discharge of the load, means for normally holding the bucket in upright position, and means under control ofthe operator for efEecting a release of the bucket to permit turning thereof, substantially as described.
